“Alexander.” Alexander of Hales, the Franciscan theologian and philosopher, Doctor Irregragabilis, was one of the greatest of the scholastics. He was born at Hales, or Hailles, in Gloucestershire towards the end of the twelfth century, and died at Paris at the convent of his Order in 1245. His principal work is the “Summa Uniuersae Theologiae,” begun about the year 1231, and left unfinished. It has several times been published: Venice, 1475, 1576; Nuremburg, 1481, 1502; Pavia, 1481; Cologne, 1622. A critical edition, which is much needed, has been promised by the Quaracchi editors of the works of S. Bonaventura.
